Referring to the drawings by characters of reference and particularly toFigs. 1, 2, and 3, there is shown a heat exchange apparatus comprising abaseboard radiator structure having a finned tube radiator or heatexchanger member generally designated by the numeral 1 which has a metaltube member or conducting pipe 2 for flow therethrough of a heatexchange medium and has a plurality of rectangular shaped fins 3,preferably of metal. The fins 3 are secured in spaced parallel relationon and in good thermal conductivity with the tube 2. The finned tuberadiator 1 is suspended in an elevated position by means of a supportingstructure generally designated by the numeral 4 which comprises abracket member 5 and a hanger member 6. The bracket member 5 ispreferably of sheet metal and has a body portion 7 and a pair of spacedparallel, horizontally extending arm mem- Patented June 18, 1957 bers 8and 9, positioned in vertical planes and which have horizontally alinedapertures 10 and 11 respectively therethrough.

The finned tube radiator 1 and the supporting structure 4 are positionedwithin a radiator enclosure having a rear panel 12 and a front 13. Therear panel 12 is secured to a wall member (not shown) of an enclosedspace or room and has a flanged base portion 14 that is constructed torest on the floor of the room and a top cover or panel portion 15 thatextends away from the wall member. The top panel portion 15 has adownward rebent flange forming hook shaped end or front securing portion16. The front panel portion 13 has a rebent downturned top edge formingan upper hook shaped end securing portion 17 and a rebent upturnedbottom edge forming a lower hook shaped end securing portion 18. Aresilient clip member 19 has at its rear end a downwardly flanged endportion 20 and at its front end an upwardly extending flanged portion 21with a downwardly extending hook shaped end portion 21. The clip member19 has its end portion 20 secured to the inside face of the rear panel12 by means of a rivet 22 or any other suitable securing means.

The bracket member body portion 7 is secured to the inner wall 12 of therear panel 12 by any suitable securing means such as spot welding. Thearm members 8 and 9 extend away or forwardly from the rear panel portion12. The body portion 7 and the arm member 9 have an upstanding angleportion with a forward flange 7 and a rear flange 7 which lies againstand is also secured to the wall 12*. The flange 7 has a finger portion23 extending forwardly from its upper end portion 9* in a direction awayfrom the rear panel portion 12. The hook shaped end securing portion 16of the top panel portion 15 hooks over and is positioned around thefinger portion 23 and is secured thereto. The upper flange portion 9 hasa horizontal flange 24 extending laterally therefrom in a planesubstantially normal to the rear panel 12 and in a plane parallel to thetop panel portion 15. The top panel portion 15 abuts the flange 24,which functions as a reinforcing and supporting member for the top panel15. The arm member 9 has a deflector supporting portions 25 with aninclined upper edge 26 and a rear vertical edge 27 which is spaced fromthe arm member flange 7 and forms a slot 27*. The deflector supportingportion 25 extends upwardly from the arm portion 9 and is operable tosupport an air deflector member 28 which has a rounded front portion 29and a downwardly flanged rear portion 30. The rear portion 30 ispositioned in the slot 27 and the rounded end portion rests against thetop front edge of the deflector supporting portion 25. The main-bodyportion of the deflector member 28 rests against the inclined edge 26and deflects the air outwardly and angularly from the inner portion ofthe radiator enclosure. The arm member 9 has another flange portion 31extending from the front edge'32 of the arm member 9 in a planesubstantially parallel to the body portion 7. The flange portion 31 hasan upwardly extending edge portion 33 around or over which the frontpanel upper hook shaped securing end portion 17 is positioned. Theflange portion 31 spaces the front panel member 13 from the rear panel12 a distance suflicient to permit positioning of the finned tuberadiator 1 therebetween. In positioning the front panel portion 13, thehook shaped end portion 17 is first positioned around or over the upperedge 33 of the flange portion 31, and the downwardly hook shaped endportion 21 of the clip member 19 is positioned around or hooked into thelower front panel hook shaped end portion 18 thereby rigidly securingthe front panel portion 13 to the supporting structure 4 and the rearpanel 12.

' The bracket member 4 has a horizontal supporting por-- tion or pinmember 34 having a flat head 35 and split end portions 36 and 37extending through the apertures and 11. The pin member 34 is secured inthe apertures 10 and 11 by means of the flat head portion 35 restingagainst the outer wall of the arm member 8, and the split end portions36 and 37 diverging away from each other beyond the outer wall of thearm member 9.

The hanger member 6 has a downwardly facing or open hook portion 38 andan upturned end portion 39. The downwardly facing hook portion 38 ispositioned on or around and supported by the pin member 34. The hangermember 6 has an upwardly facing or open hook portion and a downturnedend portion 41 which together are of substantially S-shape. The upwardlyfacing hook portion 40 is positioned around the radiator tube 2 betweena pair of the parallel fins 3. The hanger member 6 is positioned betweenadjacent fins 3 and with the end portions 39 and 41 extending toward orfacing the rear panel 12. The downturned end portion 41 extends asuflicient distance from the hook portion 40 to abut the rear panelinner wall 12 and space the finned tube radiator 1 from the rear panelportion 12. It will be noted that the end portion 41 extends beyond thefins and holds the center of gravity of the heat exchanger outward fromthe vertical line through the pin member 34 so that the heat exchangertends to swing toward the wall member 12 and away from the front panelmember 13.

When the finned tube radiator 1 is secured to the supporting structure 4as heretofore described, the hanger 6 is movable along the longitudinalaxis of the pin member 34. Therefore, to assemble the structure, theupwardly facing hook portion 40 is first positioned around and under thetube 2 and the finned tube radiator 1 is then positioned adjacent andbelow the supporting structure 4. The downwardly facing hook portion 38is then positioned around and over the pin member 34. It should be notedthat with this type of structure exact lateral spacing between thevarious places of securement of the fin tube radiator 1 to thesupporting structure 4 is not required.

One of the principal advantages of this type of hanger member andsupporting structure is that the hanger member will not bend or bedistorted due to the expansion and contraction of the finned tuberadiator which nor mally occurs during a heating or cooling cycle inaccordance with the temperature of the fluid passing through the tube 2.When the finned tube radiator is a unitary structure and extends thelength of an ordinary room, it is not uncommon for the tube to expand aconsiderable amount. In order to permit this expansion of the finnedtube radiator without the distortion or bending of the support, thefinned tube may be secured to the supporting member as shown. Uponexpansion or contraction of the finned tube radiator, the hanger member6 will rotate about a point where the downwardly facing hook shaped endportion 38 is positioned around the pin member 34 until it has rotatedto a point where the force exerted on the upwardly facing hook shapedportion 40 against the tube member 2 is greater that the frictionalforce of the downwardly facing hook shaped portion 38 on the pin member34. When the last named force exceeds the frictional force heretoforestated, the downwardly facing hook shaped portion 38 will slide alongthe longitudinal axis of the pin member 34. Thus, the hanger 6 duringperiods of slight expansion or contraction will simply rotate or rockabout a point where the downwardly hook shaped portion 38 rests on thepin member 34. If the expansion or contraction is large such as when aheating system is first put in operation, the hanger member 6 will pivotas heretofore stated until the rotated force exceeds the friction forceas heretofore stated and the hanger member 6 will then slide along thelongitudinal axis of the pin member 34. Thus, the supporting structure 4and the hanger assembly permit a relatively simple and inexpensivemethod of assembling and securing a finned tube radiator to a wallstructure and also permit the finned tube radiator to expand andcontract without bending or distorting the supporting structure or thetube fins 3.

The supporting structure 4 also functions as a means to secure the uppercover or panel portion 15 thereto, secure the air deflector memberthereto, and the front panel member of the radiator enclosure. Thus, thesupporting member functions in a dual capacity wherein it supports thehanger member which in turn supports the finned tube radiator and alsosupports and secures various parts of the radiator enclosure.

Another embodiment of this invention is shown in Figs. 4, 5, and 6. Inthis embodiment there is shown a baseboard radiator structure having afinned tube radiator member generally designated by the numeral 42 whichhas a tube member 43 and a plurality of rectangular shaped fins 44 whichare secured in spaced parallel relation to the tube 43. The finned tuberadiator 42 is suspended in an elevated position by means of asupporting structure generally designated by the numeral 45 whichcomprises a bracket member 46 preferably of sheet metal and a hangermember 47. The bracket member 46 has a body portion 48 and a pair ofspaced parallel horizontally extending arm members 49 and 50 positionedin vertical planes and which have horizontally aligned apertures 51 and52 therethrough. The finned tube radiator 42 and the supportingstructure 45 are positioned within a radiator enclosure having a rearpanel 53 and a front panel 54. The rear panel has an indented centralportion 55 and a flanged base portion 56. The rear panel 53 is securedto a wall member (not shown) of an enclosed space or room and may besecured adjacent to or spaced away from the floor. The structure shownin this embodiment may be positioned at any convenient elevation alongthe wall member, and it is not necessary that the enclosure bepositioned adjacent to the floor of the room or space to be conditioned.The rear panel portion 53 has a securing aperture 57 therethrough. Thus,the rear panel portion may be secured to a wall member by means of abolt or any other suitable securing means passing through the aperture57 to secure the rear panel portion 53 to the wall member. The rearpanel portion 53 has an outwardly and upwardly turned flange portion 57that functions to support the front panel portion 54. The rear portionlower flange 56 extends outwardly from the wall member and has a pair ofapertures 58 and 59 therethrough. A spring clip member 60 has a frontrolled portion 61 and a pair of apertures 62 and 63 therethrough. Theapertures 62 and 63 are aligned with the apertures 58 and 59 in theflange 56. A pair of rivets 64 and 64 extend through the alignedapertures and secure the spring clip member 60 to the outwardlyextending flange portion 56.

In this embodiment, the front panel portion 54 has a slotted inclinedtop portion 65 and a downwardly extending rear securing portion 66. Thesecuring portion 66 has an inwardly extending upturned flange portion 67that is positioned in the rear panel outwardly extending flange portion57" and is supported therein. The front panel portion 54 has a clipsecuring portion 63 secured to its rear wall 69. The securing clip 68has a flanged securing portion 76) that extends downward parallel to andspaced away from the front panel rear wall 69. The rear panel 53 has anelongated supporting bracket securing slot 71 and a spacer membersecuring slot 72 therein. The spacer securing slot '72 is clearly shownin Fig. 5 of the drawings. A spacer member 73 has a rear flanged portion74 and a front flanged portion 75. The flange portions 74 and 75 aresubstantially parallel to each other and normal to the body portion ofthe spacer member 73. The front flange portion 75 has an upwardlyextending securing edge portion 76 which functions to support and securethe front panel member 54 thereto. The transverse dimension of thespacer slot 72 is slightly larger than the width of the spacer member73. In positioning the spacer member 73 in the slot 72, the flanged endportion 74 is inserted in the slot 72 and the spacer member is rotatedin a clockwise direction until the flange portion 74 abuts the rear wallof the rear panel 53. In securing the front panel member 54 to the rearpanel member 53, which has been secured to the wall, the upturned rearflanged portion 67 is positioned between the wall and the upturnedflange portion 57 The spacer member securing portion 76 is positionedbetween the front panel rear wall 69 and the securing clip flangedportion 70. The spring clip front rolled portion 61 is positionedbetween the front panel rear wall 69 and the lower upturned flangeportion 77. Thus, the front panel member 54 is supported by the rearpanel 53 at the upturned flange portion 57 and by the spacer bracketflanged portion 76. The spring clip member prevents rotative movement ofthe front panel 54 and also'rigidly secures the front panel 54 to therear panel 53, thus forming a box-like enclosure with an upper slottedportion 65. It should be noted that air may enter through the bottom ofthe enclosure member between the front panel wall 54 and the rear wallflange portion 56 and leave the enclosure by means of the upper slottedportion 65.

A damper or air regulator member 78 having a body portion 79 and aflanged portion 80 is positioned within the upper portion of theenclosure. The damper 78 has a semi-circular end portion 81 extendingfrom the flanged portion 80 and forming a hinged connecting portion forthe damper member. The front panel downwardly extending securing portion66 has an inwardly bent portion 82 that has a rounded portion 83 thatfunctions as a hinge portion for the securing and supporting of thedamper member 78. A pin member 84 is inserted between the curvedportions 81 and 83 and rotatably secures the damper member 78 to thedownwardly extending front panel portion 66. The damper member rotatesabout the pin member 84 and controls the amount of air leaving theenclosure. The damper member body portion 79 has an aperture 85therethrough adjacent its lower end portion. A bead type chainpositioning member 86 is secured in the damper member aperture 85 andextends through one of the slotted portions 65 and hangs downward infront of the front panel 54. A key hole slotted guide member 87 ispositioned in one of the slots of the slotted front panel portion 65 andpermits one of the beads of the chain member 86 to rest thereon andthereby position the damper member 78 in respect to the front panelslotted portion 65. Thus, the position of the damper 78 may be regulatedby the positioning of the beads in the guide member 87. It should benoted that the damper member flanged portion 80 is so shaped that whenthe damper is in the full open position the flanged portion 80 will notinterfere with the inwardly extending rear panel flange 57 Thesupporting structure 45, as above noted, comprises a. bracket member 46and a hanger member 47. The bracket member body portion 48 has asecuring aperture 88 therethrough and an outwardly bent portion 89 whichis positioned directly below the aperture 88 and is constructed to fitwithin the slot 71. The bracket member aperture 88 is aligned with therear panel slot 71 and the outwardly bent portion 89 is inserted in theslot 71. A bolt 90 having a flat head end portion 91 is inserted in theslot 71 and extends through the bracket member aperture 88. A nut 92 isthreaded on the bolt 90 and rigidly secures the bracket member 46 to therear panel member 53. It should be noted that the bracket member 46 isvertically adjustable along the longitudinal axis of the slot'and may bemoved to its desired position within the slot 71 and rigidly secured atthis desired position by means of the nut and bolt combination. Areinforcing member 93has a body portion 94 and a pair of downwardlyextending flanged portions 95 and 96. The

6 body portion 94 has a slot 97 forming inner side walls 98 and 99. Thisslot 97 permits assembling of the hanger member 47 without interferenceof the body portion 94. The downwardly extending flange portions 95 and96 have a pair of aligned apertures 100 and 101 therethrough. Thereinforcing member 93 is positioned over the bracket member 46 with theinner walls of the downwardly extending flange portions 95 and 96abutting the outer walls of the arm members 49 and 50. The bracket armapertures 51 and 52 are aligned with the reinforcing member apertures100 and 101. A pin member 102 having a rounded head portion 103 andopposite split end portions Y104 and 105 extends through the heretoforenamed aligned apertures with the head 103 abutting the outer wall of thereinforcing flange 95 and the split end portions 104 and 105 divergingaway from each other at a point beyond the outer wall of the reinforcingmember downward flange 96.

The hanger member 47 has a body portion 106 and a pair of diverging arms107 and 108. The body portion 106 has an arcuate inner edge 109 whichprovides a hook portion that is positioned around the tube member 43.The arm 107 has an inturned or rearwardly directed flanged end 110 witha downwardly extending finger portion 111. The lower edge 112 of theflange 110 between the arm 107 and the finger 111 is curved and forms ahook shaped portion and positioned around and upon the pin member 102,thus securing the arm member 107 to the pin member 102.

In assembling the finned tube radiator 42 within the enclosure, thebracket member 45 is initially secured to the rear panel member 53 asheretofore described. The hanger member edge 109 is positioned aroundthe tube 43 and the finned tube radiator 42 is positioned below the pinmember 102. The curved edge 112 is positioned around and upon the pinmember 102, and thus the finned tube radiator 42 is suspended from thebracket member 45. It should be noted that when the hanger member is sopositioned the arm 108 abuts the rear panel 53 and spaces the fins offinned tube radiator 42 from the rear panel portion 53, thus permittingair to circulate around the rear portion of the radiator 42. Thereinforcing member 93 serves to add rigidity to the bracket member 46and the bracket member body portion outwardly bent portion 89 seating inthe slot 71 prevents rotative movement of the bracket member. Theslotted portionof the reinforcing member 93 permits the assembling andremoving of the hanger member 47 from the pin member 102 without theremoval of the reinforcing member.

This embodiment functions similarly to the embodiment shown in Figs. 1to 3 in that the hanger member 47 is laterally slidable along androckable on the pin 102, and it is deemed not necessary to againdescribe its method of operation.
